4.5.3.3 Inserting a System Board
1. Carefully insert the board (component side down if in front; component side up if
in the rear) in the proper slot in the card cage, ensuring that the board does not
slip out of the left and right card guides (
FIGURE 4-11
).

2. Ensure that both extraction levers are in the insert position (arrow pointing
outward), and that the quarter-turn access slots are unlocked (arrow indicates
unlocked position) as you slide the board toward the centerplane receptacles.
The board will not seat fully unless the levers are in this starting position and the
access slots are unlocked. See
FIGURE 4-7
, and
FIGURE 4-8
on page 4-10.
Caution – DO NOT FORCE any board into a slot; this can cause damage to the
board and system. The board should insert and seat smoothly. If it binds, remove the
board and inspect the card cage slot for any obvious obstructions. Also inspect both
the board and the centerplane for bent pins or other damage.
